The Grundfos commitment to sustainable practices leads to a water treatment and reuse system within its Demark plant

  • On August 1, 2020

In their Bjerringbro, Denmark factory Grundfos components are dipped in a series of chemical or water baths for surface treatment and rinsing, consuming about 5,000 cubic meters of water a year (about the size of two Olympic swimming pools). The water is drawn from the same underground source that is used by the townspeople for their bathing and drinking water. Grundfos has committed to a 50% reduction in water use by 2025, so they began to build a system for treating and recycling the rinsing water. The wastewater treatment is a system that sends the water through a three-filtration system, and then onward to a Grundfos reverse osmosis unit. The purified water is returned to the tanks in the factory, resulting in 80% of the water being recycled back into the water baths and the remaining being used to rinse the filters. When running at full capacity, the system is capable of treating 10,000 cubic meters of water a year, about the amount used by 200 households each year.
